Current and Forecasted Traffic Clause Samples
The "Current and Forecasted Traffic" clause defines the requirements for reporting and analyzing both present and anticipated levels of data, user, or network traffic relevant to the agreement. Typically, this clause obligates one or both parties to provide accurate information about current usage statistics and to project future traffic volumes over a specified period. This information may be used to plan for capacity, allocate resources, or determine pricing adjustments. The core function of this clause is to ensure that both parties have a clear understanding of usage patterns, enabling better operational planning and reducing the risk of service disruptions or unexpected costs.
Current and Forecasted Traffic. The District 4 Office of Planning developed the traffic forecasts for the 2062 design year on December 4, 2018. The 2022 Average Daily Traffic (ADT) on SR 87 from PM 0.0 to PM 6.1 is 208,700 vehicles. The ADT is expected to increase to a projected demand of 268,400 vehicles by 2062. Also, the 2020 percentage of trucks (% trucks) is 2.39%, and it is expected to remain at 2.39% in 2062. Table 4-5 shows the current and forecasted traffic information on SR 87 from PM 0.0 to PM 6.1 for design years 2018, 2022, 2032, 2042, and 2062.

A total of 1,048 accidents, with one fatal accident, occurred within the project limits (SR 87 from PM 0.0 to PM 6.1) during the most-recent available 3-year period (October 1, 2016, to September 30, 2019). The actual fatal accident rate is lower than the average fatal accident rate for similar facilities statewide. The fatal accident occurred on the southbound (SB) SR 87 off-ramp to Almaden Expressway on June 16, 2019, at 06:48 hours. Vehicle one (V1) was traveling at 80 miles per hour. Due to an unsafe speed, person 1 (P1) was unable to successfully negotiate the westerly curve in the roadway. This failure allowed the left rear of V1 to collide with a pile of dirt on the east side of the roadway. V1 then lost control and rotated in a counterclockwise direction, causing V1 to leave the west side of the roadway. V1 then collided with the sound wall on the west side of the roadway two times. The force by which V1 collided with the sound wall, caused V1 to overturn three times, colliding with the dirt embankment on the west side of the roadway each time. P1 sustained fatal injuries as a result of this collision. P1 caused the collision by traveling at an unsafe speed for then-current weather/traffic conditions. Table 4-6 compares the actual accident rates within the project limits with the average accident rates for similar facilities statewide during the study period. 1 340 707 1,048 0.001 0.3...

The ‘actual’ collision rate in this segment is lower than the state ‘average’ for this type of facility. There was 1 reported collision during this three-year period. This collision was a rear end accident near PM 50.5 resulting from an obstruction on the roadway. The data from the 3-year collision history indicate that the nonstandard side slopes did not contribute to any collisions. There is no recognizable or correctable trend when reviewing the 3yr collision history.

Current and Forecasted Traffic. The current and forecasted traffic data were obtained from recently conducted traffic counts as well as a Port of Los Angeles/Port of Long Beach traffic model. The existing average daily traffic (ADT) along the intersection of ▇▇▇▇▇ ▇▇▇▇▇▇▇ Boulevard and Fries Avenue north of the existing at-grade rail crossing is approximately 13,440 vehicles per day. South Wilmington Grade Separation 5 January 22, 2007 Project Study Report Equivalent Under current conditions, the at-grade railroad crossing operates at a LOS D during the peak periods when a train is present. Future (2030) traffic volumes have been estimated based on anticipated growth in through-traffic and planned/proposed terminal developments in both Ports. By the year 2030, significant increases in traffic on ▇▇▇▇▇ ▇▇▇▇▇▇▇ Boulevard and Fries Avenue will also result in LOS F operating conditions at the at-grade rail crossing. Without a railroad grade separation, unit trains accessing the West Basin would continue to cause significant delays to truck and vehicle traffic ingress/egressing West Basin destinations.
